Abstract

An experiment involving radiation reaction is proposed wherein, with the uniquely determined Lorentz-covariant radiation damping-force, the experiment provides for the detection of the absolute uniform rectilinear inertial motion of the System from purely internal operations and observations, and therewith falsifies the Principle of Relativity. This could be avoided only with the rejection of at least some one imperative requirement of the Special Relativity Theory. This rejection of an imperative requirement of Lorentz-invariance must necessarily lead to a similar experimental detection of the absolute uniform rectilinear motion of the System in some other situation, and this would again falsify the Principle of Relativity. Thus, in any case the Principle of Relativity cannot survive. As the existence of radiation back-reaction is theoretically necessary and experimentally established, the Principle of Relativity is proved to be not viable and not tenable, and stands refuted conclusively.
